I only have two plates and one is always on the printer so six slots on the original seemed to be excessive for me. I don't ever see having that many, so I chopped off 4 of the slots and shortened the back plate to remove the excess space. I also shortened the connector bar accordingly.
I found the top/front support was not needed and it made it more difficult to slide the plates in so I did not include it in my models.
I also have to use the spool rings on any cardboard spools and have extras laying around, so I added a little stub to hang them from.
The addition of the spool stub does require to print with a small support.
The author remixed this model.
